Ha! - would a madman have been so wise as this? And then, when my head was well in the room, I undid the lantern cautiously - oh, so cautiously - cautiously (for the hinges creaked) - I undid it just so much that a single thin ray fell upon the vulture eye. It took me an hour to place my whole head within the opening so far that I could see him as he lay upon his bed. Oh, you would have laughed to see how cunningly I thrust it in! I moved it slowly - very, very slowly, so that I might not disturb the old man’s sleep. And every night, about midnight, I turned the latch of his door and opened it - oh, so gently! And then, when I had made an opening sufficient for my head, I put in a dark lantern, all closed, closed, so that no light shone out, and then I thrust in my head.

You should have seen how wisely I proceeded - with what caution - with what foresight - with what dissimulation I went to work! I was never kinder to the old man than during the whole week before I killed him. Whenever it fell upon me, my blood ran cold and so by degrees - very gradually - I made up my mind to take the life of the old man, and thus rid myself of the eye forever. I think it was his eye! yes, it was this! One of his eyes resembled that of a vulture - a pale blue eye, with a film over it. It is impossible to say how first the idea entered my brain but once conceived, it haunted me day and night. How, then, am I mad? Hearken! and observe how healthily - how calmly I can tell you the whole story. I heard all things in the heaven and in the earth. Above all was the sense of hearing acute.

True! - nervous - very, very dreadfully nervous I had been and am but why will you say that I am mad? The disease had sharpened my senses - not destroyed - not dulled them.
